WARNING It is extremely important that a PC and all PC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PC System to the above-mentioned applications. 3 Safety Precautions! WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so may result in electric shock.! WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock.! WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.! WARNING Provide safety measures in external circuits (i.e., not in the Programmable Controller), including the following items, in order to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC operation. Not doing so may result in serious accidents. Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system. xvi

16 Operating Environment Precautions 4 The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. When the 24-VDC output (service power supply to the PC) is overloaded or short-circuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.! WARNING When transferring programs to other nodes, or when making changes to I/O memory, confirm the safety of the destination node before transfer. Not doing so may result in injury.! Caution Execute online edit only after confirming that no adverse effects will be caused by extending the cycle time. Otherwise, the input signals may not be readable.! Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction.! Caution When connecting a personal computer or other peripheral device to the CPM1A, either ground the 0 V side of the CPM1A or do not ground at all. Depending on the method of grounding, the 24-V power supply may short-circuit; do not ground the 24-V side as shown in the following diagram. Example: Connections where 24-V Power Supply Will Short-circuit Non-isolated DC power supply CPM1A Peripheral device 4 Operating Environment Precautions!! Caution Caution Do not operate the control system in the following places: Locations subject to direct sunlight. Locations subject to temperatures or humidity outside the range specified in the specifications. Locations subject to condensation as the result of severe changes in temperature. Locations subject to corrosive or flammable gases. Locations subject to dust (especially iron dust) or salts. Locations subject to exposure to water, oil, or chemicals. Locations subject to shock or vibration. Take appropriate and sufficient countermeasures when installing systems in the following locations: xvii

17 Application Precautions 5! Caution Locations subject to static electricity or other forms of noise. Locations subject to strong electromagnetic fields. Locations subject to possible exposure to radioactivity. Locations close to power supplies. The operating environment of the PC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PC System. Be sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system. 5 Application Precautions Observe the following precautions when using the PC System.! WARNING Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury.! Caution Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω or less may result in electric shock. Always turn off the power supply to the PC before attempting any of the following. Not turning off the power supply may result in malfunction or electric shock. Mounting or dismounting I/O Units, CPU Units, or any other Units. Assembling the Units. Connecting or wiring the cables. Connecting or disconnecting the connectors. Failure to abide by the following precautions could lead to faulty operation of the PC or the system, or could damage the PC or PC Units. Always heed these precautions. Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes. Construct a control circuit so that power supply for the I/O circuits does not come ON before power supply for the Unit. If power supply for the I/O circuits comes ON before power supply for the Unit, normal operation may be temporarily interrupted. If the operating mode is changed from RUN or MONITOR mode to PROGRAM mode, with the IOM Hold Bit ON, the output will hold the most recent status. In such a case, ensure that the external load does not exceed specifications. (If operation is stopped because of an operation error (including FALS instructions), the values in the internal memory of the CPU Unit will be saved, but the outputs will all turn OFF.) Always use the power supply voltage specified in the operation manuals. An incorrect voltage may result in malfunction or burning. Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction. Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning. xviii

18 Application Precautions 5 Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may result in burning. Do not apply voltages or connect loads to the Output Units in excess of the maximum switching capacity. Excess voltage or loads may result in burning. Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning. Install the Unit properly as specified in the operation manual. Improper installation of the Unit may result in malfunction. Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction. With version-1 CPU Units, leave the label attached wiring in order to prevent wiring cuttings from entering in the Unit. With pre-version-1 CPU Units, be sure to attach the supplied labels when wiring in order to prevent wiring cuttings from entering in the Unit. Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction. Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning. Double-check all the wiring before turning on the power supply. Incorrect wiring may result in burning. Be sure that the terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction. Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected operation. Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation. Changing the operating mode of the PC. Force-setting/force-resetting any bit in memory. Changing the present value of any word or any set value in memory. Resume operation only after transferring to the new CPU Unit the contents of the DM and HR Areas required for resuming operation. Not doing so may result in an unexpected operation. Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables. Do not place objects on top of the cables. Doing so may break the cables. When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning. Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in malfunction or damage. Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order to prevent any malfunction due to static electricity. When using a thermocouple-input type Temperature Sensor Unit, observe the following precautions: Do not remove the cold junction compensator attached at the time of delivery. If the cold junction compensator is removed the Unit will not be able to measure temperatures correctly. Each of the input circuits is calibrated with the cold junction compensator attached to the Unit. If the Unit is used with the cold junction compensator from other Units, the Unit will not be able to measure temperatures correctly. xix

19 Application Precautions 5 Do not touch the cold junction compensator. Doing so may result in incorrect temperature measurement.! Caution Always clear memory before beginning to program the CPM1A. Although memory is cleared before the CPU Unit is shipped (except for bits with specific functions), AR 1314, which turns ON when the internal capacitor cannot back up memory, may have turned ON during shipment.! Caution If the CPM1A will be turned off for periods exceeding the data backup period of the internal capacitor, design the system so that it will not be influenced if data in the DM, HR, and CNT areas is cleared when power is turned off.! Caution Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655). The user program and memory area data in the CPM1A are backed up either by an internal capacitor or in flash memory as shown in the following table. Backup method Internal capacitor Flash memory Data Read/write DM area (DM 0000 to DM 0999, DM 1022, and DM 1023) Error log area (DM 1000 to DM 1021) HR area (HR 00 to HR 19) Counter area (CNT 000 to CNT 127) User program Read-only DM area (DM 6144 to DM 6599) PC Setup (DM 6600 to DM 6655) Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is turned off and all contents will be cleared the next time power is turned on. (The PC Setup setting in DM 6601 can be used to back up this data. Refer to details on the PC Setup later in this manual for details.) 2. The bits in the AR and SR areas have special functions and are set according to these functions when power is turned on. The capacitor backup time depends on the ambient temperature, as shown in the following graph. The backup time, however, assumes that the capacitor is fully charged, which requires that power be supplied to the CPU Unit continuously for at least 15 minutes. Backup time (days) Ambient temperature ( C) xx

20 EC Directives 6 6 EC Directives 6-1 Applicable Directives 6-2 Concepts If the power remains off for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor will be cleared. AR 1314 will remain ON unless it is turned OFF using I/O monitor operations, using memory clear operations, or from the user program. If desired, the PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON. The data stored in flash memory will not be lost even if power remains off for a period exceeding the data backup period, because the data stored in flash memory will be read to the CPU Unit when the CPM1A is turned on. If the power is turned off without changing the mode from PROGRAM mode to RUN or MONITOR mode after having made changes in the data that is backed up in flash memory, the changes will not be written to flash memory. If the power is then left off for more than 20 days (at 25 C), the changes (i.e., the contents of the RAM) will be erased and the data values will become undefined. EMC Directives Low Voltage Directive EMC Directives OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer. EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards. Note Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Susceptibility): EN EMI (Electromagnetic Interference): EN (Radiated emission: 10-m regulations) Low Voltage Directive Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to 1,500 VDC meet the required safety standards for the PC (EN ). 6-3 Conformance to EC Directives All CPM1A CPU Units with model numbers ending in -V1 conform to EC directives. The following restrictions apply to CPM1A CPU Units with model numbers not ending in -V1. Relay Output Units and Transistor Output Units of CPU Units with DC power supplies conform to EC Directives. Relay Output Units, however, conform to EC Directives only when the output load power supply is outside the ranges specified for the Low Voltage Directive (less than 75 VDC or less than 50 VAC). Relay Output Units and Transistor Output Units of CPM1A CPU Units with AC power supplies do not conform to EC Directives. xxi

21 EC Directives 6 All Expansion I/O Units except for the CPM1A-20EDR conform to EC Directives. To ensure that the machine or device in which the CPM1A PC is used complies with EC Directives, the PC must be installed as follows: 1, 2, The CPM1A PC must be installed within a control panel. 2. Reinforced insulation or double insulation must be used for the DC power supplies used for the PC and I/O power supplies. 3. CPM1A PCs complying with EC Directives also conform to the Common Emission Standard (EN ). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives. 6-4 Relay Output Noise Reduction Methods All CPM1A CPU Units with model numbers ending in -V1 conform to the Common Emission Standards (EN ) of the EMC Directives. For CPM1A CPU Units with model numbers not ending in -V1, Relay Output Units and Transistor Output Units of CPU Units with DC power supplies conform to the Common Emission Standards (EN ) of the EMC Directives. Relay Output Units, however, conform to the Common Emission Standards (EN ) only when the output load power supply is outside the ranges specified for the Low Voltage Directive (less than 75 VDC or less than 50 VAC). When a Unit is built into another device, however, it may not satisfy these standards due to noise generated by relay output switching. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PC. Countermeasures taken to satisfy the standards vary depending on the devices on the load side, wiring, configuration of machines, etc. Following are examples of countermeasures for reducing the generated noise. Countermeasures Refer to EN for more details. Countermeasures are not required if the frequency of load switching for the whole system including the PC is less than 5 times per minute. Countermeasures are required if the frequency of load switching for the whole system including the PC is more than 5 times per minute. Countermeasure Examples When switching an inductive load, connect a surge protector, diodes, etc., in parallel with the load or contact. For detailed circuit examples, refer to the relevant parts of this manual. 6-5 CPM1A-MAD01 Conformance to EMC Directives Immunity testing conditions when using the current I/O of the CPM1A-MAD01 are as follows. Total accuracy: +10%/-1% Insert the following core in each line as shown below. Recommended core: xxii

22 Revised Specifications 7 Manufacturer: Fair Rite Products Corp. 7 Revised Specifications The following table shows the changes that have been made in product specifications beginning with lots produced in January 1998 (December 1997 for some models). Item Previous specifications New specifications Relevant pages Input indicator operation when an error occurs Memory holding operation of built-in capacitor The input indicators will maintain the current status and will not change with the status of the input signal when a memory error, no END instruction error, or system error occurs. If the power remains OFF for a period exceeding the data backup period, the capacitor will not be able to back up data and the status of the data backed up by the capacitor (Read/write DM area, Error log area, HR area, and Counter area) will become unstable. The input indicators will change with the status of the input signal when a memory error, no END instruction error, or system error occurs. If the power remains OFF for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor (Read/write DM area, Error log area, HR area, and Counter area) will be cleared. The PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON. Item 8., Input Indicators, on page 33.

As a result, a memory error will be displayed if the I/O comment area is set (although no actual memory error has occurred). CX-Programmer can be used to set the I/O comment area in the CPU Unit, and I/O comments can be set together with programs. See information on UM Area allocation in the WS02-CXPC1-EV3 CX-Programmer Operation Manual (W414) and the WS02-CXPC1-E-V4 CX-Programmer Operation Manual (W425). The following table shows the changes that have been made in product specifications beginning with the introduction of version-1 Units in May 2001 (April 2001 for some models). Item EC Directives Model numbers External appearance Output specifications ca s Terminal blocks External dimensions Relay outputs Transistor outputs New specifications (V1 models) All products with model numbers ending in -V1 conform to EC Directives. -V1 was added to the end of the model numbers. The arrangement of input, output, and operation indicators was changed. The shape of the I/O connector was changed. The mechanical life of output relays was increased from 10 to 20 million operations. The fuse was eliminated for both sourcing and sinking outputs. The functional earth terminal was eliminated (i.e., converted to an NC terminal) on CPU Units with AC power supplies. The depth of CPU Units with AC power supplies was decreased from 85 mm to 70 mm. xxiv

26 CPM1A Features and Functions Section CPM1A Features and Functions CPM1A Features One-piece Construction The CPM1A CPU Units feature a one-piece construction including 10, 20, 30, or 40 built-in I/O terminals. The following three model groups are available: relay output models, sinking transistor output models, and sourcing transistor output models. CPU Units with 10 I/O Points CPM1A-10CD - -V1 CPM1A-10CD - CPU Units with 20 I/O Points CPM1A-20CD - -V1 CPM1A-20CD - CPU Units with 30 I/O Points CPM1A-30CD - -V1 CPM1A-30CD - CPU Units with 40 I/O Points CPM1A-40CD - -V1 CPM1A-40CD - Extra I/O Capacity Up to three Expansion I/O Units can be connected to a CPM1A-30CD - (-V1) or CPM1A-40CD - (-V1) CPU Unit to add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points. Input Filter Function The CPM1A is equipped with a filter function to prevent incorrect operation caused by chatter or noise in the input signal. The user can select an input time constant of 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms. Low-maintenance Design Flash memory provides memory backup without a battery. Input Interrupts The CPM1A-10CD - (-V1) CPU Units can handle 2 interrupt inputs; the CPM1A-20CD - (-V1), CPM1A-30CD - (-V1), and CPM1A-40CD - (-V1) CPU Units can handle 4 interrupt inputs. In addition to normal input interrupts, the CPM1A has a counter mode that counts high-speed input signals and triggers interrupts at fixed count multiples. Quick-response Inputs Quick-response inputs can detect input signals with a pulse width as short as 0.2 ms regardless of their timing during the PC cycle. Quick-response inputs and interrupt inputs use the same input terminals. 2

27 CPM1A Features and Functions Section 1-1 Interval Timer High-speed Counter Pulse Output Function Analog Setting Function Analog I/O Units CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to 319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or repeat scheduled interrupts (scheduled interrupt mode). CPM1A PCs have a high-speed counter that can be used in incremental mode or up/down mode. The high-speed counter can be combined with input interrupts to perform target value control or zone comparison control that isn t affected by the PC s cycle time. The CPM1A transistor output models have an output function capable of outputting a pulse of 20 Hz to 2 khz (single-phase output). The CPM1A PCs have 2 analog volume controls that can be used to make manual analog settings. Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs. Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 analog inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O Units. Unit Analog inputs Analog outputs CPM1A-MAD01 Signal range: 0 to 10 V, 1 to 5 V, or 4 to 20 ma, Resolution of 1/256 The open-circuit detection function can be used with the 1 to 5 VDC and 4 to 20 ma settings. CPM1A-MAD11 Signal range: 0 to V 5, 0 to 10 V, 1 to 5 V, 10 to 10 V, 0 to 20 ma, or 4 to 20 ma, Resolution of 1/6,000 The open-circuit detection function can be used with the 1 to 5 VDC and 4 to 20 ma settings. Signal range: 0 to 10 V, 10 to 10 V, or 4 to 20 ma, Resolution of 1/256 Signal range: 0 to 10 V, 1 to 5 V, 10 to 10 V, 0 to 20 ma, or 4 to 20 ma, Resolution of 1/6,000 Temperature Sensor Units Host Link Communications One-to-one PC Link NT Link Communications CompoBus/S I/O Link Units A Temperature Sensor Unit can be connected to provide up to 6 inputs for temperature input from sensors, such as thermocouples or platinum resistance thermometers. Temperature Sensor Unit Functions Thermocouple input (CPM1A-TS001/002; 2/4 input points): K: 200 to 1,300 C ( 300 to 2,300 F) 0.0 to C (0.0 to F) J: 100 to 850 C ( 100 to 1,500 F) 0.0 to C (0.0 to F) Platinum resistance thermometer input (CPM1A-TS101/102; 2/4 input points): Pt100: to C ( to 1,200.0 F) JPt100: to C ( to 1,200.0 F) The CPM1A PCs are compatible with the Host Link, which allows communications with personal computers. The CPM1A using the Host Link can also communicate with Programmable Terminal using host link commands. An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is used for 1:N communications. A data link can be created with a data area in another CPM1A, CQM1, CPM1, SRM1 or C200HS or C200HX/HG/HE PC. An RS-232C Adapter is used to make the 1:1 connection. High-speed operations can be achieved by providing a direct access by connecting the CPM1A to the OMRON Programmable Terminal through the NT Link Interface. An RS-232C Adapter is used for this connection. Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (internal) and 8 output bits (internal). 3

28 CPM1A Features and Functions Section 1-1 The CompoBus/S Network provides distributed CPU control based on a PC + compact PC configuration, which is an improvement on the earlier distributed I/O control based on a PC + remote I/O configuration. The distributed CPU control makes equipment modular, so designs can be standardized, special needs can be addressed, and modules can be replaced easily in the event of a breakdown. Master PC CompoBus/S Master Unit (or SRM1 CompoBus/S Master Control Unit) CPM1A (Slave) CompoBus/S I/O Link Unit CompoBus/S Distributed CPU control DeviceNet I/O Link Units Standard Peripheral Devices Programming is Possible Using the PT Expansion Memory Unit DeviceNet I/O Link Units can be connected to enable using the CPM1A as a DeviceNet slave. Up to 32 internal input and 32 internal outputs points are supported for each Unit, and up to 3 Units can connected. DeviceNet application allows networks to be constructed including devices from other manufacturers. The CPM1A uses the same Programming Consoles and SYSMAC Support Software (SSS) as the C200H/HS, C200HX/HG/HE, CPM1, SRM1, and CQM1 PCs. Programming operation is possible through the PT screen by using an OMRON PT that has a built-in Programming Console function. The CPM1-EMU01-V1 Expansion Memory Unit is a program loader for smallsize or micro PLCs. Using the CPM1-EMU01-V1, simple on-site transfer of user programs and data memory is possible with PLCs.

Increasing the input time constant can reduce the effects of chatter or noise in the input signal. Input from an input device such as a limit switch Input bit status t t Input time constant With the CPM1A, actual response time for each set input time constant for word 000 is different from that for word 001 or later. Set value Word 000 Word 001 or later 1 ms 1 to 1.5 ms 0.1 to 0.3 ms 2 ms 2 to 2.5 ms 0.7 to 1.5 ms 4 ms 4 to 4.5 ms 1.5 to 2.5 ms 8 ms 8 to 8.5 ms 3 to 4.5 ms 16 ms 16 to 16.5 ms 6 to 9 ms 32 ms 32 to 32.5 ms 12 to 18 ms 64 ms 64 to 64.5 ms 24 to 35 ms 128 ms 128 to ms 50 to 70 ms The input response time of the CPM1A is obtained with the following: 2 ms max. (hardware performance) + input time constant (see above table) + cycle time Input Interrupts The CPM1A-10CDR- (-V1)/10CDT-D(-V1)/10CDT1-D(-V1) PCs have 2 interrupt input terminals and the CPM1A-20CDR- (-V1)/20CDT- D(-V1)/20CDT1-D(-V1), CPM1A-30CDR- (-V1)/ 30CDT-D/30CDT1-D(-V1), and CPM1A-40CDR- (-V1)/40CDT-D(-V1)/40CDT1-D(-V1) PCs have 4 interrupt input terminals. There are two modes for input interrupts: input interrupt mode and counter mode. 1, 2, When an interrupt occurs in Input Interrupt Mode, the main program is interrupted and the interrupt program is executed immediately, regardless of the cycle time. 2. In Counter Mode, external input signals are counted at high speed (up to 1 khz) and an interrupt is generated each time the count reaches the set value. When an interrupt occurs, the main program is interrupted and the interrupt program is executed. The set value can be set from 0 to 65,535. 6

Caution Although IORF(97) can be used in interrupt subroutines, you must be careful of the interval between IORF(97) executions. If IORF(97) is executed too frequently, a fatal system error may occur (FALS 9F), stopping operation. The interval between executions of IORF(97) should be at least 1.3 ms + total execution time of the interrupt subroutine. 7

32 CPM1A Features and Functions Section 1-1 Quick-response Inputs The CPM1A-10CDR- (-V1)/10CDT-D(-V1)/10CDT1-D(-V1) PCs have 2 quick-response input terminals and the CPM1A-20CDR- (-V1)/20CDT- D/20CDT1-D(-V1), CPM1A-30CDR- (-V1)/30CDT-D(-V1)/30CDT1-D(-V1) and CPM1A-40CDR- (-V1)/40CDT-D(-V1)/40CDT1-D(-V1) PCs have 4 quick-response input terminals. (The same terminals are used for quick-response inputs and interrupt inputs.) Quick-response inputs have an internal buffer, so input signals shorter than one cycle can be detected.

The timer can be set to trigger a single interrupt (one-shot mode) or to trigger scheduled interrupts (scheduled interrupt mode). Main program MOV ADD Interval timer time-out Interrupt program SBN00 MOV END RET Pulse Output Function One-shot Mode Scheduled interrupt Function Generates a single interrupt the first time that the timer times out. Generates an interrupt each time that the timer times out. Since the CPM1A with transistor output has a pulse output function capable of outputting a pulse of 20 Hz to 2kHz (single-phase output), a stepping motor can be controlled by the CPU Unit alone. 8

33 CPM1A Features and Functions Section 1-1 The pulse output can be set to either the continuous mode, under which the output can be stopped by an instruction, or the single mode, under which the output can be stopped by the preset pulse rate (1 to 16,777,215). Stepping motor Stepping motor Control input Motor controller Pulse output (single-phase output) CW/CCW control output High-speed Counter CPM1A PCs have a high-speed counter that can be used in incremental mode or up/down mode.

36 System Configuration Section CPU Unit and Expansion Unit Up to 3 Expansion I/O Units or Expansion Units can be connected to a CPU Unit with 30 or 40 I/O points. There are three types of Expansion Units available: Analog I/O Units, Temperature Sensor Units, the CompoBus/S I/O Link Unit, and the DeviceNet I/O Link Unit. Expansion Connector Expansion I/O Unit: Analog I/O Unit, Temperature Sensor Unit, Compo- Bus/S I/O Link Unit, or DeviceNet I/O Link Unit Expansion I/O Connecting Cable A PC with 100 I/O points (the maximum) can be assembled by connecting three Expansion I/O Units. CPM1A-40CD - (24 inputs, 16 outputs) CPM1A-20EDR1 1 Unit + 3 Units = 60 inputs, 40 outputs (12 inputs, 8 outputs) A PC with 6 analog inputs and 3 analog outputs (the maximum) can be assembled by connecting three Analog I/O Units. A PC with up to 6 temperature inputs for input from thermocouples or platinum resistance thermometers can be assembled by connecting Temperature Sensor Units. CompoBus/S I/O Link Units (Slave Units) can be connected to a CPU Unit. I/O data (8 inputs and 8 outputs) is transferred between the CPU Unit and the area allocated to the CompoBus/S Slave. (The I/O data exchanged with the Slave is internal data; there are no external input or output terminals.) Up to three DeviceNet I/O Link Units can be connected to a CPU Unit. Each DeviceNet I/O Link Unit enables using the CPM1A as a DeviceNet slave with 32 input and 32 output points. Note Different types of Expansion Units can be connected at the same time. For example, an Expansion I/O Unit, Analog I/O Unit, and CompoBus/S I/O Link Unit, or an Expansion I/O Unit, Analog I/O Unit, and Temperature Sensor Unit can be connected to the CPU Unit.

Memory Backup The user program and memory area data in the CPM1A are backed up either by an internal capacitor or in flash memory as shown in the following table. Backup method Internal capacitor Flash memory Data Read/write DM area (DM 0000 to DM 0999, DM 1022, and DM 1023) Error log area (DM 1000 to DM 1021) HR area (HR 00 to HR 19) Counter area (CNT 000 to CNT 127) User program Read-only DM area (DM 6144 to DM 6599) PC Setup (DM 6600 to DM 6655) Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is turned off and all contents will be cleared the next time power is turned on. (The PC Setup setting in DM 6601 can be used to back up this data. Refer to details on the PC Setup later in this manual for details.) 2. The bits in the AR and SR areas have special functions and are set according to these functions when power is turned on. The capacitor backup time depends on the ambient temperature, as shown in the following graph. The backup time, however, assumes that the capacitor is fully charged, which requires that power be supplied to the CPU Unit continuously for at least 15 minutes. Backup time (days) Ambient temperature ( C) If the power remains off for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor will be cleared. AR 1314 will remain ON unless it is turned OFF using I/O monitor operations, using memory clear operations, or from the user program. If desired, the PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON. 24

48 Specifications Section I/O Specifications The data stored in flash memory will not be lost even if power remains off for a period exceeding the data backup period, because the data stored in flash memory will be read to the CPU Unit when the CPM1A is turned on. If the power is turned off without changing the mode from PROGRAM mode to RUN or MONITOR mode after having made changes in the data that is backed up in flash memory, the changes will not be written to flash memory. If the power is then left off for more than 20 days (at 25 C), the changes (i.e., the contents of the RAM) will be erased and the data values will become undefined. Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

64 SECTION 3 Installation and Wiring This section provides information on installing and wiring a CPM1A PC. Be sure to follow the directions and precautions in this section when installing the CPM1A in a panel or cabinet, wiring the power supply, or wiring I/O. 3-1 Design Precautions Power Supply Wiring Interlock and Limit Circuits Power Supply Voltage CPM1A Power Interruptions Selecting an Installation Site Installation Site Conditions Panel/Cabinet Installation Installing the CPM1A CPM1A Orientation CPM1A Installation Connecting an Expansion I/O Unit Wiring and Connections General Precautions for Wiring Ground Wiring Power Supply Wiring Input Wiring Output Wiring Peripheral Device Connection Host Link Connections One-to-one PC Link Connections One-to-one NT Link Connections CompoBus/S I/O Link Unit Connections DeviceNet I/O Link Unit Connections

65 Design Precautions Section Design Precautions Power Supply Wiring Interlock and Limit Circuits Observe the following precautions when designing a system incorporating a CPM1A PC. Separate the power supply wiring from the control system, CPM1A system, and DC I/O system wiring. Separate the control circuits that supply power to the main Unit from the main circuits using dedicated circuit protectors and fuses.! WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits (i.e., not in the Programmable Controller) to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC operation. Not providing proper safety measures may result in serious accidents. Construct an external interlock circuit if CPM1A outputs are used to perform reciprocal operations such as controlling the forward and reverse operation of a motor or if incorrect PC operation could cause accidents or mechanical damage. Also, construct an external limit circuit to prevent run-away movement in systems such as position control. The following diagram shows an example of an interlock circuit. Interlock Circuit MC2 MC1 Motor forward CPM1A MC1 MC2 Motor reverse Power Supply Voltage In the interlock circuit above, MC1 and MC2 can t be ON at the same time even if CPM1A outputs and are both ON (an incorrect PC operation).! Caution Use the power supply voltages indicated in Section 2 Unit Specifications and Components. Failure to adhere to the specifications may result in fire. In places where power supply conditions are poor, take steps to ensure that power is supplied at the rated voltage. Be sure to adhere to safety precautions, such as providing breakers to prevent short circuits in external wiring. When conducting any of the following operations, turn OFF the power to the PC. Electric shock, product damage and malfunction may result. Connecting or disconnecting Expansion I/O Units and CPU Units. Assembling Units Connecting cables and wiring CPM1A Power Interruptions Supply Voltage Drop When the supply voltage falls below 85% of the rated value, the PC will stop and the outputs will go OFF. 42

66 Selecting an Installation Site Section 3-2 Momentary Power Failure Detection A momentary power failure lasting less than 10 ms with an AC power supply and 2 ms with a DC power supply is not detected and the CPU Unit continues to operate. A momentary power failure lasting longer than 10 ms with an AC power supply and 2 ms with a DC power supply may or may not be detected in an uncertain area. When a momentary power failure is detected, the CPU Unit stops operating and the output goes OFF. Automatic Restart When the supply voltage recovers to a value higher than 85% of the rated value, operations resumes automatically. Duration of power interrupt (Below 85% of rated voltage) Under Normal operation 10 ms (2 ms) Over Operation may stop. All outputs go OFF when operations stop. Note The CPM1A may repeat stop/start operations if the supply voltage of less than 85% of the rated value gradually goes up or down. If this affects the equipment, etc., provide a protection circuit which shuts off the output if the supply voltage is not above the rated value. 3-2 Selecting an Installation Site Time Up to the Start of Operation The time from when the power supply is turned on to when the operation starts varies depending on the operation conditions such as power supply voltage, configuration, ambient temperature, etc. The minimum time is approximately 300 ms. The CPM1A is resistant to harsh conditions and highly reliable, but installing the PC in a favorable site will maximize its reliability and operating lifetime.! Caution Be sure to install the CPM1A correctly, as outlined in this manual. Failure to do so may result in Unit malfunction Installation Site Conditions Note Do not install the CPM1A under any of the following conditions. Locations subject to direct sunlight. Locations subject to a temperature below 0 C or over 55 C. Locations subject to a humidity below 10% or over 90%. Locations subject to condensation as the result of severe changes in temperature. Locations subject to corrosive or flammable gases. Locations subject to dust (especially iron dust) or salts. Locations subject to shock or vibration. Locations subject to exposure to water, oil, or chemicals. Be sure that the conditions at the installation site conform to the CPM1A s general specifications. Refer to General Specifications for details. 43

67 Selecting an Installation Site Section Panel/Cabinet Installation Note Provide proper shielding when installing in the following locations: Locations subject to static electricity or other sources of noise. Locations subject to strong electromagnetic fields. Locations subject to possible exposure to radiation. Locations near to power supply lines. Consider PC operation, maintenance, and surrounding conditions when installing the CPM1A in a panel or cabinet. Overheating The operating temperature range for the CPM1A is 0 C to 55 C. Be sure that there is adequate ventilation for cooling. Allow enough space for air circulation. Do not install the CPM1A above equipment that generates a large amount of heat, such as heaters, transformers, or large resistors. Install a cooling fan or system when the ambient temperature exceeds 55 C. Control panel Fan CPM1A Air vent Electrical Noise Power lines and high-voltage equipment can cause electrical noise in the PC. Do not install the CPM1A in a panel or cabinet with high-voltage equipment. Allow at least 200 mm between the CPM1A and nearby power lines. 200 mm min. CPM1A 200 mm min. Accessibility Ensure that the CPM1A can be accessed for normal operation and maintenance. Provide a clear path to the CPM1A for operation and maintenance. High-voltage equipment or power lines could be dangerous if they are in the way during routine operations. The PC will be easiest to access if the panel or cabinet is installed about 3 to 5 feet off of the floor. 44

82 Wiring and Connections Section 3-4 Leakage Current (24 VDC) A leakage current can cause false inputs when using 2-wire sensors (proximity switches or photoelectric switches) or limit switches with LEDs. False inputs won t occur if the leakage current is less than 1.0 ma (2.5 ma for IN00000 to IN00002), but if the leakage current exceeds these values, insert a bleeder resistor in the circuit to reduce the input impedance, as shown in the following diagram. Input power supply Bleeder resistor 2-wire sensor, etc. R CPM1A I: Device s leakage current (ma) R: Bleeder resistance (kω) W: Bleeder resistor s power rating (W) L C : CPM1A s input impedance (kω) I C : CPM1A s input current (ma) E C : CPM1A s OFF voltage (V) = 5.0 V R L C 5.0 k max. W 2.3 I L C 5.0 R Wmin. The equations above were derived from the following equations: I Input voltage (24) R Input Current (I C ) Input voltage (24) R Input Current (I C ) OFF voltage (E C : 5.0) Input voltage (24) W Input voltage (24) tolerance (4) R Refer to I/O Specifications for details on the values L C, I C, and E C. The input impedance, input current, and OFF voltage may vary depending on the input being used. (IN00000 through IN00002 have different values.) Sensor Surge Current If a sensor power supply is turned ON when the PC is ON and ready to receive inputs, surge current from the sensor may result in an incorrect input. To prevent improper operation, use the following type of programming in the ladder program to delay accepting inputs from a sensor from when the sensor is turned ON until the sensor reaches stable operation TIM 0000 # : Sensor power supply voltage detection Time required for sensor to stabilize (for OMRON Proximity Sensor): 100 ms TIM : Input from sensor Note The SV of TIM 000 can be set to #0001 (0.1 s) to achieve a delay time of 100 ms, but the timer accuracy is 0 to 0.1 s, meaning that the timer s Completion Flag may turn ON immediately after the timer input. The SV must thus be set to #0002 (0.2 s) or higher to allow for timer accuracy. Inductive s When connecting an inductive load to an input, connect a diode in parallel with the load. The diode should satisfy the following requirements: 1, 2, Peak reverse-breakdown voltage must be at least 3 times the load voltage. 59

101 Support Software Capabilities Section Support Software Capabilities SSS System Setup The SSS is a complete programming and control package designed for C-series and CVM1 PCs. It provides not only programming capabilities, but also advanced debugging, monitoring, and program/data management. The following tables provide only a brief introduction to the capabilities of the SSS. For further information and actual operating procedures, please refer to the SYSMAC Support Software Operation Manuals: Basics and C-series. CPM1A programming can be performed with any version of the SSS. In addition, the SYSMAC-CPT can be used for programming the CPM1A. Refer to the SYSMAC-CPT Support Software Quick Start Guide (W332) and User Manual (W333) for operation procedures. When programming the CPM1A using the SYSMAC-CPT, be sure to set the PC model on the Support Software to CPM1 (CPM1A). Operations for the WS02-CXPC1-E CX-Programmer are provided in the WS02-CXPC1-EV3 CX-Programmer Operation Manual (W414) and the WS02-CXPC1-E-V4 CX-Programmer Operation Manual (W425). Set the PC Model to CQM1 and the PC Interface to PERIPHERAL. Follow the directions in the SSS operating manuals for other System Setup settings. PC Model PC Interface If the CPM1A PC doesn t appear as an option in the SSS s System Setup, set the PC Model to CQM1. The CPM1A is compatible with the CQM1. Set the PC Interface to the Peripheral Device Port by selecting PERIPHERAL from the submenu. After selecting the Peripheral Device Port, set the communications baud rate to 9,600 baud CPM1A Restrictions and Precautions When programming the CPM1A, set the PC Model on the SSS to CQM1. Heed the following restrictions when programming the CPM1A. Programming Check Since the data area of the CQM1 is larger than that of the CPM1A, some parts of the area cannot be checked as the CPM1A PC. Pay careful attention to the usable data area when programming. Note If a program that contains addresses not supported by the CPM1A are transferred to the CPM1A, a memory error will occur when operation is begun and AR 1308 will turn ON. Refer to the Programming Manual (W353) for differences in memory areas. Memory Usage Expansion Instructions Since the memory of the the CQM1 is larger than that of the CPM1A, the displayed available memory capacity is larger than the actual available memory capacity. Pay careful attention to the actual available memory capacity when programming. When a program is transferred after changing the assignment of function codes for the 18 expansion instructions, a message to Turn on the DIP switch of the PC and execute again is displayed. Change the assignment of the function codes for the expansion instructions to the default settings before programming. The default settings for the CQM1 are as shown in the following table. 78

142 SECTION 5 Test Runs and Error Processing This section describes procedures for test runs of CPM1A operation, self-diagnosis functions, and error processing to identify and correct the hardware and software errors that can occur during PC operation. 5-1 Initial System Checks and Test Run Procedure Initial System Checks CPM1A Test Run Procedure Flash Memory Precautions The CPM1A Cycle Self-diagnosis Functions Non-fatal Errors Fatal Errors Identifying Errors User-defined Errors Programming Console Operation Errors Programming Errors Troubleshooting Flowcharts Maintenance Inspections Handling Precautions

143 Initial System Checks and Test Run Procedure Section Initial System Checks and Test Run Procedure Initial System Checks Note Check the following items after setting up and wiring the CPM1A. Be sure to check the wiring and connections before performing a test run. Item Power supply and I/O connections Connecting cables Dustproof label Points to check Is the wiring correct? Are the terminals securely tightened? Are there any shorts between crimp connectors or wires? Refer to 3-4 Wiring and Connections for details. Are the cables all connected correctly and locked? Refer to 3-4 Wiring and Connections for details. Has the dustproof label been removed? Note 1. Always clear memory before beginning to program the CPM1A. Although memory is cleared before the CPU Unit is shipped (except for bits with specific functions), AR 1314, which turns ON when the internal capacitor cannot back up memory, may have turned ON during shipment. 2. If the CPM1A will be turned off for periods exceeding the data backup period of the internal capacitor, design the system so that it will not be influenced if data in the DM, HR, and CNT areas is cleared when power is turned off. 3. Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655) CPM1A Test Run Procedure 1, 2, Power Supply Application a) Check the CPM1A s power supply voltage and terminal connections. b) Check the I/O devices power supply voltage and terminal connections. c) Turn on the power supply and check that the PWR indicator lights. d) Use a Peripheral Device to set the CPM1A to PROGRAM mode. 2. I/O Wiring Checks a) With the CPM1A in PROGRAM mode, check the output wiring by turning on the output bits with the force set and force reset operations. Refer to Force Set, Reset for details. b) Check the input wiring with the CPM1A s input indicators or a Peripheral Device s monitor operations. 3. Test Run a) Use a Peripheral Device to set the CPM1A to RUN or MONITOR mode and check that the RUN indicator lights. b) Check the sequence of operation with the force set/reset operations, etc. 4. Debugging Correct any programming errors that are detected. 5. Saving the Program a) Use a Peripheral Device to write the program to a backup floppy disk. b) Print out a hard copy of the program with a printer. Note Refer to Section 4 Using Peripheral Devices for details on SYSMAC Support Software or Programming Console operations. 120

144 Initial System Checks and Test Run Procedure Section Flash Memory Precautions Observe the following precautions to protect the flash memory and ensure proper operation. 1, 2, If the power is turned off without changing the mode after having made changes in the read-only DM area (DM 6144 through DM 6599), or PC Setup (DM 6600 through DM 6655), the contents of changes will not be written to flash memory. Therefore, if the power is turned off for more than 20 days (at 25 C), contents of changes (contents of the RAM) will disappear and the data values will become undefined values. For details, refer to Characteristics. The changes can be saved by switching the CPM1A to RUN or MONITOR mode or turning on the CPM1A soon after the changes are made. 2. When the CPM1A is operated for the first time after changing the program, the read-only DM area (DM 6144 through DM 6599) or PC Setup (DM 6600 through DM 6655) will take about 600 ms longer than usual. Be sure to take this one-time startup delay into account. 3. If one of the following three operations is performed in MONITOR or RUN mode, the CPM1A will extend the cycle time for up to 600 ms and interrupts will be disabled while the program or PC Setup is being overwritten. Program changes with the online edit operation Changes to the read-only DM area (DM 6144 through DM 6599) Changes to the PC Setup (DM 6600 through DM 6655) A SCAN TIME OVER error won t occur during these operations. The CPM1A s I/O response times may be affected when the online edit operation is being performed. 121

145 The CPM1A Cycle Section The CPM1A Cycle The overall flow of CPM1A operation is as shown in the following flowchart. The CPM1A is initialized internally when the power is turned on. If no errors are detected, the overseeing processes, program execution, I/O refreshing, and Peripheral Device servicing are executed consecutively (cyclically). The average cycle time can be monitor from a Peripheral Device. Power application Initialization processes Initialization Check hardware and Program Memory. No Check OK? Yes Overseeing processes Set error flags and activate indicators. Preset cycle time monitoring time. ERROR or ALARM? ALARM (flashing) Execute user program. ERROR (lit) End of program? No Program execution Yes Check cycle time setting. Minimum cycle time set? No Cycle time Yes Cycle time processing Wait until minimum cycle time expires. Compute cycle time. Refresh input bits and output terminals. I/O refreshing Service peripheral port. Service peripheral port. Note Initialization processes include clearing the IR, SR, and AR areas, presetting system timers, and checking I/O Units. 122

146 Self-diagnosis Functions Section Self-diagnosis Functions The CPM1A is equipped with a variety of self-diagnosis functions to help identify and correct errors that might occur and reduce down time. PC errors are divided into 2 categories based on the severity of the errors. Fatal errors are more serious errors which stop CPM1A operation. Non-fatal errors are less serious and don t stop CPM1A operation Non-fatal Errors PC operation and program execution will continue after one or more of these errors have occurred. Although PC operation will continue, the cause of the error should be corrected and the error cleared as soon as possible. When one of these errors occurs, the POWER and RUN indicators will remain lit and the ERR/ALM indicator will flash. Message FAL No. Meaning and appropriate response SYS FAIL FAL** (** is 01 to 99 or 9B.) 01 to 99 An FAL(06) instruction has been executed in the program. Check the FAL number to determine conditions that would cause execution, correct the cause, and clear the error. 9B An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and correct as directed. AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to DM 6614) when power was turned on. Correct the settings in PROGRAM Mode and turn on the power again. AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to DM 6644) when switching to RUN Mode. Correct the settings in PROGRAM Mode and switch to RUN Mode again. AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to DM 6655) during operation. Correct the settings and clear the error. SCAN TIME OVER F8 Watchdog timer has exceeded 100 ms. (SR will be ON.) This indicates that the program cycle time is longer than recommended. Reduce cycle time if possible. (The CPM1A can be set so that this error won t be detected.) Communication Errors (no message) None If an error occurs in communications through the peripheral port, the COMM indicator will be off. Check the connecting cables and restart. Check the error flags in AR 0812 ON Fatal Errors PC operation and program execution will stop and all outputs from the PC will be turned OFF when any of these errors have occurred. CPM1A operation can t be restarted until the PC is turned off and then on again or a Peripheral Device is used to switch the PC to PROGRAM mode and clear the fatal error. All CPU Unit indicators will be OFF for the power interruption error. For all other fatal operating errors, the POWER and ERR/ALM indicators will be lit. The RUN indicator will be OFF.! WARNING The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. External safety measures must be provided to ensure safety in the system. Not providing proper safety measures may result in serious accidents. 123

147 Self-diagnosis Functions Section 5-3 Message Power interruption (no message) FALS No. None Meaning and appropriate response Power has been interrupted for at least 10 ms (2 ms for DC power types.)

AR 1312 ON: A checksum error has occurred in the program. Check the program and correct any errors detected. AR 1314 ON: The internal capacitor can no longer back up data. Clear the error and check/correct the contents of the data areas backed up by the capacitor. NO END INST F0 END(01) is not written in the program. Write END(01) at the end of the program. I/O BUS ERR C0 An error has occurred during data transfer between the CPU Unit and Expansion I/O Unit. Check the Expansion I/O Unit s connecting cable. I/O UNIT OVER E1 Too many I/O Units have been connected. Check the I/O Unit configuration. SYS FAIL FALS** (** is 01 to 99 or 9F.) 01 to 99 A FALS(07) instruction has been executed in the program. Check the FALS number to determine the conditions that caused execution, correct the cause, and clear the error. 9F The cycle time has exceeded the FALS 9F Cycle Time Monitoring Time (DM 6618). Check the cycle time and adjust the Cycle Time Monitoring Time if necessary Identifying Errors PC errors can be identified from error messages displayed on the Programming Console, error flags in the SR or AR areas, and the error code in SR to SR Error Messages Error Flags Error Code Error messages generated by the self-diagnosis function can be read from a Programming Console or host computer running SYSMAC Support Software. When the self-diagnosis function detects a hardware error, it will turn on the corresponding error flags in the SR and AR areas. When an error is detected by the self-diagnosis function, the corresponding error code is written to SR to SR (The error code is an 2-digit hexadecimal code.) User-defined Errors There are three instructions that the user can use to define his own errors or messages. FAL(06) causes a non-fatal error, FAL(07) causes a fatal error, and MSG(46) sends a message to the Programming Console or host computer connected to the PC. FAILURE ALARM FAL(06) FAL(06) is an instruction that causes a non-fatal error. The following will occur when an FAL(06) instruction is executed: 1, 2, The ERR/ALM indicator on the CPU Unit will flash. PC operation will continue. 2. The instruction s 2-digit BCD FAL number (01 to 99) will be written to SR to SR The FAL numbers can be set arbitrarily to indicate particular conditions. The same number cannot be used as both an FAL number and an FALS number. To clear an FAL error, correct the cause of the error and then execute FAL 00 or clear the error using the Programming Console. 124

148 Programming Errors Section 5-5 SEVERE FAILURE ALARM FALS(07) FALS(07) is an instruction that causes a fatal error. The following will occur when an FALS(07) instruction is executed: MESSAGE MSG(46) 1, 2, Program execution will be stopped and outputs will be turned OFF. 2. The ERR/ALM indicator on the CPU Unit will be lit. 3. The instruction s 2-digit BCD FALS number (01 to 99) will be written to SR to SR The FALS number and time of occurrence will be recorded in the PC s error log area if a Memory Cassette with a clock (RTC) is used. The FALS numbers can be set arbitrarily to indicate particular conditions. The same number cannot be used as both an FAL number and an FALS number. To clear an FALS error, switch the PC to PROGRAM Mode, correct the cause of the error, and then clear the error using the Programming Console. MSG(46) is used to display a message on the Programming Console. The message, which can be up to 16 characters long, is displayed when the instruction s execution condition is ON. 5-4 Programming Console Operation Errors The following error messages may appear when performing operations on the Programming Console. Correct the error as indicated and continue with the operation. Refer to the SYSMAC Support Software Operation Manuals: Basics and C-series PCs for errors that may appear when operating the SSS. Message REPL ROM PROG OVER ADDR OVER SETDATA ERR I/O NO. ERR Meaning and appropriate response An attempt was made to write to write-protected memory. Set bits 00 to 03 of DM 6602 to 0. The instruction at the last address in memory is not NOP(00). Erase all unnecessary instructions at the end of the program. An address was set that is larger than the highest memory address in Program Memory. Input a smaller address. FALS 00 has been input, and 00 cannot be input. Reinput the data. A data area address has been designated that exceeds the limit of the data area, e.g., an address is too large. Confirm the requirements for the instruction and re-enter the address. 5-5 Programming Errors These errors in program syntax will be detected when the program is checked using the Program Check operation. 125

149 Programming Errors Section 5-5 Three levels of program checking are available. The desired level must be designated to indicate the type of errors that are to be detected. The following table provides the error types, displays, and explanations of all syntax errors. Check level 0 checks for type A, B, and C errors; check level 1, for type A and B errors; and check level 2, for type A errors only. Type Message Meaning and appropriate response A????? The program has been damaged, creating a non-existent function code. Re-enter the program. CIRCUIT ERR The number of logic blocks and logic block instructions does not agree, i.e., either LD or LD NOT has been used to start a logic block whose execution condition has not been used by another instruction, or a logic block instruction has been used that does not have the required number of logic blocks. Check your program. OPERAND ERR NO END INSTR LOCN ERR JME UNDEFD DUPL SBN UNDEFD STEP ERR A constant entered for the instruction is not within defined values. Change the constant so that it lies within the proper range. There is no END(01) in the program. Write END(01) at the final address in the program. An instruction is in the wrong place in the program. Check instruction requirements and correct the program. A JME(05) instruction is missing for a JMP(04) instruction. Correct the jump number or insert the proper JME(05) instruction. The same jump number or subroutine number has been used twice. Correct the program so that the same number is only used once for each. The SBS(91) instruction has been programmed for a subroutine number that does not exist. Correct the subroutine number or program the required subroutine. STEP(08) with a section number and STEP(08) without a section number have been used incorrectly. Check STEP(08) programming requirements and correct the program. B IL-ILC ERR IL(02) and ILC(03) are not used in pairs. Correct the program so that each IL(02) has a unique ILC(03). Although this error message will appear if more than one IL(02) is used with the same ILC(03), the program will executed as written. Make sure your program is written as desired before proceeding. JMP-JME ERR JMP(04) and JME(05) are not used in pairs. Make sure your program is written as desired before proceeding. SBN-RET ERR If the displayed address is that of SBN(92), two different subroutines have been defined with the same subroutine number. Change one of the subroutine numbers or delete one of the subroutines. If the displayed address is that of RET(93), RET(93) has not been used properly. Check requirements for RET(93) and correct the program. C COIL DUPL The same bit is being controlled (i.e., turned ON and/or OFF) by more than one instruction (e.g., OUT, OUT NOT, DIFU(13), DIFD(14), KEEP(11), SFT(10)). Although this is allowed for certain instructions, check instruction requirements to confirm that the program is correct or rewrite the program so that each bit is controlled by only one instruction. JMP UNDEFD JME(05) has been used with no JMP(04) with the same jump number. Add a JMP(04) with the same number or delete the JME(05) that is not being used. SBS UNDEFD A subroutine exists that is not called by SBS(91). Program a subroutine call in the proper place, or delete the subroutine if it is not required. 126
